Ajinomoto Side Effects
Ajinomoto Side Effects

Monosodium Glutamate commonly known as Ajinomoto is one of the main ingredients of many Chinese food items.

Still, most of the people don’t know its side effects on our health. Children and pregnant woman are more vulnerable to it.

Just one decade back, we use to love mom-made, home-cooked food. Eating outside was very rare and even not needed.

The yummy and healthy Parathas are loaded with ghee; all simple, home-cooked food was the only thing you would think about. The fashion of pizza, chips, and Maggie has just recently come into vogue.

Yep, Time has changed. All ready to cook and instant food are readily available everywhere, even at your home.

I know that people are literate enough. They are aware now of the ingredients and the nutritional content of the item, but why do they turn their eyes against something like MSG, a slow killer.

The worst ingredient present in almost all prepared food items is the monosodium glutamate. Big name? This element comes from the name of Ajinomoto.

What is this? How does it harm you? All these questions will be answered in the following article.

Ajinomoto is nothing but a Japanese firm named Ajinomoto Corp..It produces this Ajinomoto food enhancer.

Its main ingredient is this monosodium glutamate commonly known as MSG. It enhances the flavor of the food items. This ingredient is increasingly found in many prepared foods.

Previously only Chinese food contained this ingredient. But, now it has moved from Chinese restaurants to our kitchen shelves.

The noodles that you eat wafers that you enjoy and 1 min soup packet you feel yummy are all slow killers. All these essential food items contain MSG (monosodium glutamate).

Below is the reason as to why is this ingredient so harmful and how does it harm our body.

How This MSG Is Made & Why Is It So Harmful?

When you eat items containing MSG or glutamic acid, then the glutamate levels in the blood increases by about 8-10 times. Normally this level should be very low in the blood. Due to this excess level, it causes severe effects.

Also, the Ajinomoto ingredients is an excitatory neurotransmitter. It over stimulates the nerve cells. Excess intake of this ingredient upsets the balance of the neurotransmitter. This imbalance leads to an unhealthy body and also adverse consequences.

Why do people use it even after knowing everything? This is the question that hits me often. Look, MSG is quite cheap and is readily available in the market. It enhances the food taste so that people like you, long for more. With low costs, food chains will get huge profits.

Another reason is that when you take MSG, it stimulates your pancreas. Pancreas then releases the insulin even when your sugar level is fine. This excess insulin causes a drop in the sugar standards of the body, and you feel hungry. This leads to overeating along with obesity.

MSG is addictive too. If you eat items containing MSG once, you tend to get into the habit of eating that food item on a regular basis.

Ajinomoto Side Effects:

I have been repeating this line many times that MSG is a slow killer. The health effect that it has at first are quite mild. But with the expense of time, they become severe.

Instead of having many Side effects the product is still very much used in our day to day life.

Here below is the list of some Side effects caused by this dangerous ingredient.

  • A headache: This is a very common side effect of MSG. You normally get it. But due to continuing intake of MSG, this mild headache can take the form of a migraine. This migraine can be very severe.
  • Overstimulates the nerves: As already discussed MSG is a neurotransmitter. It stimulates the nerves and misbalances the neurotransmitters. This leads to an unhealthy body.
  • Heart effects: Excess intake doesn’t even leave heart unaffected. It leads to irregular heartbeats, cardiac muscles arrest, and Chest pains.
  • Pregnant women have to be very cautious regarding this ingredient. It causes sterility in pregnant women. During pregnancy, Ajinomoto should have been avoided the cause of its side effect.
  • Even small kids should completely avoid consumption of MSG.
  • MSG can be a reason for proble
  • ms like blood pressure, thyroid issues, diabetes, asthma, food allergies and also obesity.
  • Nausea and weakness can also be felt after consumption of MSG.
  • It can also damage the retina of the eyes.
  • This ingredient can also be a reason for causing cancer.

Items That Contain MSG:

  • Ready to eat food packets
  • Dehydrated soup packets
  • Dehydrated gravy packets
  • Instant noodles and cup noodles.
  • Preserved fish
  • All kinds of sausages
  • Tomato ketchup
  • Mayonnaise
  • Potato wafers
  • Soya sauce
  • All canned and preserved foods
  • All fast food items, mainly Chinese

These food items should be completely avoided. If you don’t, you are risking your life to an ingredient that will kill you slowly.

Prefer food items made at home, basically organic and unprocessed food. I’m not saying that you should never eat these things. You can make all these things at home without the use of this dangerous MSG.

After knowing all this, I’m pretty sure that you will avoid all kinds of prepared food items. Not completely, but still you will try.

See, life is very precious. Don’t pay high prices just for satisfying your taste buds. I will just say maintain one thing “say no to Ajinomoto or this ingredient MSG.”

Ensure that when you eat out, there is no MSG added to the food item. When you buy products to make sure that they are free of MSG.

    Cite medical references please. Your only reference is Wikipedia and that says “however, in controlled studies scientists have been unable to trigger such reactions consistently”.

  • Jason

    Seems like you are just writing based on your perception rather than based on medical references

  • Anubrata Bhattacharya

    the levels of msg in foods are not high enough to cause any side effects. Also, our blood brain barrier (BBB) is not permeable to glutamate so it does not enter the brain. Glutamate salts are naturally present in most basic foods such as fish, meat, cheese. Yes, people with gout, uricemia and asthma problems should not consume excess of glutamate.

  • Al-Shahim

    Basically, as of this writing… Ajinomoto or the so called MSG is still an URBAN LEGEND. I am 63 years old and have been consuming food containing Ajinomoto… I am in the state of depression now, “THEN WHY THE HECK AJINOMOTO’s EFFECT IS STILL NOT TAKING ITS TOLL”…Well, SLOW KILLER indeed. 🙁

    • Thanks for sharing your experience.Infact whole generation has been going through this without knowing its side effect.Yes you are right,its slow killer.It might not kill you but its side effect will make you life worse.

      • Greg Easter

        How can there be a “side effect” from consuming a tiny bit of something that your own body produces in large amounts naturally? This is pseudoscience at its worst – fear mongering by someone pretending to be an expert on a topic they clearly don’t know the first thing about.

  • Greg Easter

    More ignorant fear mongering from a quack. Your own body PRODUCES glutamate in large amounts every day. You would quite literally die without it. Furthermore, it is not the “main ingredient” in ANY dish. It is used in very small amounts. Do you even understand what the term “main ingredient” means? What an idiot.

    None of what you say has been clinically proven. Also, the US FDA has MSG listed under it’s GRAS section. The same section under which items like sugar, salt, etc. fall under. That being said, ANYTHING consumed without moderation is potentially harmful.

  • eat healthy….be healthy

    If its so harmful…then why the hell it isn’t banned yet?

    • Yes this is a biggest concern we have too.Artificial sweetener aspartame, fluoride toothpastes and there are many more items are there which are not banned but these products are harmful.

  • Rebecca Lee

    We, from young been taking Ajinomoto. Even my late mother in law. My late parent and late mother in law were taking Ajinomoto too. None of them had any funny sickness . All died after 88 years old. My late grandma and her children all were taking Ajinomoto and my late grandma passed away at the age of 101 and her son is 102 this year still alive and he always remember all his nieces and nephew ! His little brother is 92 but 1 of his ear is partially deaf due to sickness.

    We add in Ajinomoto not by spoons but by pinch only.

    I saw a video of 60 Americans were invited for free Chinese lunch but none of them knew that they were eating Ajinomoto or not but Chinese food = headache, irregular heartbeats, cardiac muscles arrest and Chest pains, felt like vomiting and so on.

    When meal finished, the host asked who were not feeling well,7 of them said that they were.

    The Chef came out from the kitchen told them that the Right handside tables served no Ajinomoto added in their food, that shocked them.

    5 guests from the Right handside had above mentioned signs but they didn’t take any Ajinomoto food.

    That 2 guests from the Left handside who had Ajinomoto added in their food but 1 of them was too delighted as she met her Love at 1st Sight man who sat next to her that caused her to have irregular heartbeats.

    So bottom line, in the past reports of many stuffs are not good, eg, egg yolks, coconut milk. But 3 years ago they found out that both are high in Cholesterol BUT have the more HDL which is good cholesterol then the LDL, the bad cholesterol.

  • dan

    You know that organic nature grown tomatoes also contain MSG right?

  • anonymous

    how about reading up on wikipedia? mono sodium glutamate is not an externally aquired substance. even natural foods such as tomatoes and cheese have naturally occering mono sodium glutamate in them. mono sodium glutamate is metabolised in large quantities by our body too, which is naturally produced during protein hydrolysis. a person simply cant avoid a susbtance that is naturally present in a lot of natural food items, and also synthesised b our body.

    i know i am ranting, but there is a huge misconception in most of the households about MSG being bad for health.

    • therebel

      i agree… if ajinomoto was such a problem, why dont everybody in china have a headach?

      • It is harmful.If we follow your logic then Tobaco cause cancer then why don’t call the person who smoke don’t have this.
        Its your choice.We are creating more awareness to help you live a healthy life.

  • veer

    Thank you very much sir for providing valuable information, as of we all all known that artificial food products makes harm. Also, waste food always taste is too good, when compared with home food.

  • Jason

    All your reference U.S.FDA & FSANZ stated MSG is safe for consumption and your quote into your article of saying MSG is deadly? Do you even read the content before posting as your reference and you call yourself a doctor? Seems more like a page trying to use MSG to boost readership! Disgrace to writers & doctors!

    • francis b

      so it seems. He didnt seem to read or notice that all his reference were in fact stating MSG is safe to consume. However, for some people with higher sensitivity, it may cause certain symptoms like headache…neverthless, people wont eat MSGs directly with a mouthful of it…. almost all hotdogs have MSGs….

    Ajinomoto or chemically sodium glutamate is naturally found in our body. In fact glutamate is extremely important for our well being, It is also found naturally in the commonest of foods such as chicken, shrimp, prawn, tomato, cheese, soybean etc. But of course there should be a limit to how much you consume it. Even excess intake of Salt will cause the symptoms that you mentioned. Ajinomoto is as harmful or harmless as Common Salt. Well, I have a masters degree in biochemistry and I am sorry to say the writer of this article is misleading the common people.
